Facebook is secretly working on its own OS; will it replace Android? The social networking giant, Facebook is reportedly developing its own operating system (OS) from scratch. The OS will power Facebook's smart hardware products including augmented reality (AR) and virtual reality (VR) headsets. By creating its own OS, Facebook will integrate more indigenous features that are currently missing from Facebook's smart devices. Facebook has a range of products including Oculus VR headsets and video calling devices like Portal video calling devices. These devices currently powered by Google's Android OS . The company has not indicated any plan to create an OS for smartphones. The OS project is led by Mark Lucovsky, a former Microsoft engineer who built the Windows NT operating system. While there is no official confirmation on which products Facebook will be using this OS for, Portal video-calling devices will get the OS before Oculus VR headsets. Andrew Bosworth, V
